There is not much information about the serial connection in that
document.

But there is some accessories for the serial connection

Is the information in that document sufficent to write a rs232-serial-
driver for NUT?

It looks a nice toy for low power devices, indeed. And its onboard RS232 
, by the lack of Rx/Tx , is the oddest one I've seen in 30+ years since 
I deal with serial interfaces ( burnt the first one in '87 on my 
Commodore 64 ). OTOH it seems that , after connecting the "μExtension 
Modul" the serial starts to behave like a regular one ( that is, it has 
all the usual pins and signals ). I guess that a driver for it could be 
written by a passionate who has access to a board, given that 
https://www.bicker.de/files/downloads/handbuch/benutzerhandbuch-users-manual-psz-1063.pdf 
seems to provide the communication protocol. OTOH, RS232 in 2022 seems a 
bit .. ancient, the world transitioned to USB a long time ago. But 
looking at the electronic schemes they include, I kind of understand the 
reasoning behind their choice... although a USB interface is not so hard 
to implement nowadays.

It looks like the Pinebook Pro has a /sys/class/power_supply driver:

https://github.com/Syonyk/pinebookpro/blob/master/pbp-status.sh#L10 


so theoretically, you could poll that interface and export some data for 
dummy-ups, as suggested in this thread:

https://alioth-lists.debian.net/pipermail/nut-upsuser/2016-September/010300.html
 


Admittedly, a compiled NUT driver for Linux power_supply devices would be 
better:

[Nut-upsuser] Some unsupported UPS

The Pine64 ARM boards have a battery connector, not quite a laptop, but
AFAIK the board will charge and use the battery as fallback if lights
go out.
